We’re at a crucial point in time where we’re finally starting to understand the unexpected problems caused by synthetic chemicals.  One of the biggest issues is plastic—a man-made material that has become woven into our everyday lives.

Just this week, a study published in Nature Medicine served as a powerful reminder of the hidden dangers of microplastics—tiny particles of plastic that end up in our bodies. These microscopic bits are being found in places we never expected, and scientists are only beginning to uncover how they might be affecting our health.

The study brought to light a disturbing reality: the human brain contains approximately a spoonful of microplastics and nanoplastics (MNPs), with levels three to five times higher in individuals diagnosed with dementia. These tiny fragments of degraded plastic are being ingested at alarming rates, and scientists are only just beginning to understand the long-term effects on human health.

Research suggests that microplastics may contribute to inflammation, hormone disruption, and cellular damage. In mouse models, exposure to nanoplastics led to learning and memory deficits, neuroinflammation, and a reduction in synaptic proteins—clear indicators that could hint at a link between microplastic exposure and cognitive decline in humans.

The issue doesn’t stop there. A recent study published in The New England Journal of Medicine found that individuals with carotid artery plaques containing MNPs faced a significantly higher risk of heart attacks and strokes. And people with inflammatory bowel disease (IBD) were found to have 50% more microplastics in their stool compared to healthy individuals, pointing to a potential link between MNP exposure and chronic inflammatory conditions.

Perhaps most concerning is the revelation that bottled water is the largest contributor to microplastic exposure—with an estimated 90,000 particles consumed per year by those who drink it regularly.

Completely eliminating microplastic exposure is, sadly, unrealistic. These particles are embedded in every aspect of modern life—from bottled water and processed foods to air pollution and household dust. However, we are not entirely powerless.

Practical steps to reduce exposure include:

• Switching from bottled water to filtered tap water, which cuts annual microplastic intake from 90,000 to 4,000 particles.

• Avoiding plastic containers, especially when heating food, to reduce ingestion. Opt for glass or stainless steel alternatives.

• Inducing sweating through exercise or sauna use, which some research hints may help eliminate plastic-derived compounds like BPA from the body.

While more studies are needed to confirm whether sweat can reduce microplastic accumulation, making these lifestyle changes is a logical and proactive approach to minimising exposure.
